Trunnion Mounts
Trunnion Mounts
Joyce trunnion adapter plates bolt to the base of 2-ton through 20-ton machine screw or ball screw jacks and ComDRIVEs. They include precision bores for trunnion pins. These are frequently used in installations where a single jack moves through an arc during operation. This jack is often configured with a motor mount or as a ComDRIVE.
Protective Boots for Translating and Keyed Design Machine Screw Jacks
Protective Boots for Translating and Keyed Design Machine Screw Jacks
Joyce boots protect the lifting screw from dust, dirt, and help maintain lubrication. Standard boots, fabricated from neoprene-coated nylon also guard against moisture and corrosive contaminants. Adding protective boots may increase the closed height of jacks. For specific dimensional information based on jack design, refer to the information below.
